Climate Change

Here's What The World Will Look Like Once All The Ice Melted. Terrifying!
We learned last year that many of the effects of climate change are irreversible.

Sea levels have been rising at a greater rate year after year, and the Intergovernmental Panel on Climate Change estimates they could rise by another meter or more by the end of this century. As National Geographic showed us in 2013, sea levels would rise by 216 feet if all the land ice on the planet were to melt.
Humans Are Changing the Climate 170x Faster Than Natural Forces. A New Equation Scientists have devised a new mathematical equation that allows them to determine just how much humans are affecting the climate.

According to the researchers, global temperatures have decreased by an average of 0.01 Celsius per century over the last 7,000 years. This figure is what they considered the baseline rate. In the last 45 years however, trends show that it has increased at 1.7 Celsius per century, due to greenhouse gas emissions. In the paper, published in the journal The Anthropocene Review, the researchers go on to explain that across billions of years, Earth’s climate has been dependent on astronomical and geophysical forces, as well as internal dynamics of the planet.
Massive hurricane-force Atlantic storm to push abnormally mild air toward North Pole.

(National Weather Service Ocean Prediction Center) A gigantic, powerhouse winter storm is charging through the North Atlantic and promises to flood the high Arctic with abnormally mild air. Arctic temperatures have blown past previous record highs in recent months, and this surge of (relative) warmth is just the latest in a long series that has amazed scientists.

Global Carbon Atlas. Thermohaline Circulation - Fact Sheet by Stefan Rahmstorf. As opposed to wind-driven currents and tides (which are due to the gravity of moon and sun), the thermohaline circulation (Fig. 1) is that part of the ocean circulation which is driven by density differences.

Sea water density depends on temperature and salinity, hence the name thermo-haline. The salinity and temperature differences arise from heating/cooling at the sea surface and from the surface freshwater fluxes (evaporation and sea ice formation enhance salinity; precipitation, runoff and ice-melt decrease salinity). Heat sources at the ocean bottom play a minor role.
Graph of the Day: World has warmest winter on record. [Not just the Arctic experiences the warmest winter on record – this goes for the entire globe, new NASA data show.

The massive Greenland ice sheet is shedding about 300 gigatons of ice a year into the ocean, making it the single largest source of sea level rise from melting ice. Credits: NASA/Saskia Madlener Sea level rise is a natural consequence of the warming of our planet.
Flooding of Coast, Caused by Global Warming, Has Already Begun. NORFOLK, Va. — Huge vertical rulers are sprouting beside low spots in the streets here, so people can judge if the tidal floods that increasingly inundate their roads are too deep to drive through.

Five hundred miles down the Atlantic Coast, the only road to Tybee Island, Ga., is disappearing beneath the sea several times a year, cutting the town off from the mainland. And another 500 miles on, in Fort Lauderdale, Fla., increased tidal flooding is forcing the city to spend millions fixing battered roads and drains — and, at times, to send out giant vacuum trucks to suck saltwater off the streets. For decades, as the created by human emissions caused land ice to melt and ocean water to expand, scientists warned that the accelerating rise of the sea would eventually imperil the United States’ coastline.
